BFG GS-550 ATX Power Supply - 500W, SATA-Ready

Comment:
I got this PSU for a new Rig I had NCIX build me. IT's currently running an EVGA NFORCE 750I MB, Intel Core 2 Quad Q9550, and a GTS 250 without any problems at all. It's a great supply for your budget-medium builds.

Comment:
Great for cheap build when you get this on sale, otherwise not much more can be said about it other than it looks good but again its not 80PLUS so dont expect top notch efficiency either..

Comment:
For the sale price paid, I'm happy with these units (have 2). They are reasonably weighted, quiet and all the lines are neatly sleeved. Good finish and all the connectors I needed to use on mid-range systems. However... I would be disappointed had I paid regular price, given its power capability (see other reviewers comments).

Comment:
My unit exhibits coil whine when there is no load on the 5v line. It fortunately is not loud enough to irritate me.

Comment:
This PSU is a nice PSU for a mid power system, a GTX 250. A dual or quad core cpu. Works well and is quiet. This review was modfied by poster @ 06-02-09 11:40 AM

At $40 on sale you get a very good PSU for a budget build that you won't have to worry about 'blowing up' and taking components from your computer with it.BFG is a brand name PSU that puts out quality products that are miles ahead of the generic paperweight PSUs you'd normally get at the sale price. It does what it's supposed to do, run a decent computer without any hiccups.As for weaknesses, you get what you pay for, this PSU is really only about a 400W on load and normal operating conditions; and it's about half the weight of the equivalent Corsair or Seasonic series PSUs.

This works without any issues is pretty quiet . With the 4+4 12V power removes some clutter better solution than some of my other power supplies that have an unused 4 or 8 pin power connector as I haven't come across a board that needs both. Would have been nice if the cables were modular but I can't complain for the low price.Very good deal would buy again.

First off, don't expect this to be a true 550W psu. It's probably closer to 350-400W. However, this thing is pretty ...it looks/feels very nicely built and they didn't skimp on materials. It's worth it when it's on sale for $40, when you're only powering a low-end system. Amazingly, cables are sleeved at this price. It's also got a big fan that moves a decent amount of air quietly.Gonna be the prettiest thing in my older system. Did I mention this thing is pretty and shiny? =)

A buddy and I each grabbed one of these PSU's when they went on sale a few weeks ago.One was used to replace a Seasonic 350WThe other was used on a new Core2Duo system.When compared with the Seasonic, the GS550 is definitely more powerful, and pushes more air through for cooling, but when it came to noise standards the Seasonic is easily the quieter option. But, that's pretty much the end of the bad news for this well priced unit.The Core2Duo system was as follows:Core2Duo E74004Gb XMS2Seagate 7200.12 500GbSamsung DVD+RWeVGA 250GTS Superclockedeverything is running factor-set speeds. No OC up to now.I am not a professional when it comes to power supplies, but the power supply seems to stay solid within 5% on voltages when playing games and priming. The noise level COULD be better, but it is within reason when given its price, and power rating. Just for the record this is not supposed to compare to BFG's previous high-spec power supplies. This is more mainstream, sold in bix-box stores.The cables are nicely sleeved in black mesh, long enough for its use, and can be easily cable managed. Even when used inside a bottom-mount tower case, the CPU plug is still sufficiently long to reach the top of the board.HOWEVER, the CPU power cord will likely not be long enough in a case bigger than the Antec 900!The unit does not have Active PFC, but BFG promised up to 85% efficiency, which should be an upside, if the ratings are true.At the standard price, there are better options, but if it's on special, and your requirement is something short of a quad-core + dual VGA, this unit will power everything just fine. This PSU was a wise choice for me. This review was modfied by poster @ 05-01-09 12:33 AM

For the sale price of $40, this is a decent PSU. I wouldn't pay full price (currently $75.57) for it, though. The 140mm fan seems quiet enough, and it powers a very underwhelming system (Phenom 9500 & Gigabyte mATX board). Currently, it's happily sitting at the bottom of an Antec 300 case with the fan facing *down*. The power output should be sufficient for almost all usages, with the exceptions of high-end gaming and server use. The cable sheaths have a UV-reactive pattern on them that can only be seen when the black light is turned on - nice touch!

paid 40 dollars for it. looks good and works great. a little bit noisy. would buy it again. bfg always makes good product.

Paid 40$ on sale. Great value for the price. Louder than my Corsair PSU but for the price I can't complain much. 3 years warranty is good. This review was modfied by poster @ 04-20-09 07:14 PM

I have 2 of these, and one of them is still going strong. The other one however recently died while I was hot-swapping some hard drives over. I've tried everything to get it going, but so far no luck. After this I'll stick to BFG's graphics cards and leave their power supplies alone.I would give it 2 stars if I could, but I don't have my order number.

Comment:
My only gripe with this PSU is that the housing is larger than my 620w Enermax. Overall a good quality product and wasn't that expensive.

Comment:
Came packaged really nicely. Was pretty... but, when I turned it on it wouldn't turn off! Also, the fan inside was sounding like it was rubbing on something. Sent it back... gonna try a coolermaster. NCIX RMA'd it for me.

I bought this power supply for $40 bucks on a Suprise sale. Excellent Addition to my gaming system. It powers my Sapphire Radeon HD 4830, 500GB SATA2 HDD, DVD Burner, Intel E5200 CPU, 1x120mm and 1x140mm Fans very well. Cables also have sufficient length in my Antec 300 Case.

Got this on sale for $50 and it has been powering my 9800gt quad core setup. It's a great psu for the price and BFG always make good product, I wouldn't hesitate to recommend this to my friends.

Comment:
Works great in my HTPC setup.Not as quiet as I hoped, but pretty close. Maybe soon they'll make easy to get no-fan power supplies

Comment:
I bought this for a low power HTPC application on the weekly sale and it works without any issues (It's quiet enough). 4+4 12V power removes some clutter (better solution than some of my other power supplies that have an unused 4 or 8 pin power connector as I haven't come across a board that needs both). Would have been nice if the cables were modular but I can't complain for the price. Here's hoping it lasts.
