Thermaltake Smart BX1 550W Bronze SLI/Crossfire Ready Continuous Power ATX12V v2.3 / EPS v2.92 80 Plus Bronze Certified 5 Year Warranty Non Modular Power Supply PS-SPD-0550NNFABU-1 80+ Bronze 550W Power

Satisfied. Good product at a reasonnable price.

First thing I'll mention is that I received a used/returned unit, which was very obvious. Everything was there and other than a label that was slightly peeling, it was a fully functioning working unit. I can't blame manufacturers for reselling all the stuff that's RMA'd due to inexperienced computer builders. I've used at least 3 of these in recent builds and all continue to work well after 9+ months. Only complaint is that some motherboards have two 12V EPS connectors (CPU) and this PSU only has one. In practice it makes no difference because most motherboard/CPU combos don't need the second connector, but it would be nice to have the second one installed. I love the sleeved multi-colored & ketchup/mustard wiring, it makes diagnosing PCs so much easier. Nothing worse than diagnosing all black wiring and having to look up connector pinouts to see which one is which. I use these PSUs for customers, and I don't like modular wiring because they might need to add something in the future, which in that case you'd have to leave the extra wires connected anyways for that purpose. I used to buy another brand for these types of builds (obviously these aren't high end gaming systems) that is no longer available, but this has been a great alternative for the price and has a gold efficiency rating. Zero complaints so far, and very quiet while in use.

What a gem this turned out to be. Quiet is an understatement. It simply whispers. Outstanding investment. High quality purchase. Excellent product.

have used these in a back up gaming pc build for my son and daughter and they are fantastic value In a 600w units!!! I also a 850 gold for my RC battery charger. My charger when I'm charging my 2-3s 5000mah packs in parallel 6 batteries per channel on both channels so 12x 3s 5000 mah lipo packs I'm charinging at 70 amps. My Icharger 406 duo is capable of 40 amps per channel and 70 amps if running both channels. So it's pushing out 840watts during the charge cycles and it handles it with no issues what so ever. No thermal issues when demanding 840 watts from it contentious and voltage stays locked in. The 850w gold I've had for seems about 2 years now and it's used to charge pretty much every single day. Some times it's 12x 5000mah packs parallel charged one set after the next when my kids and I are flying and or driving rc cars, boats, planes.. my icharger 406 duo and this power supply do very well together for rapid charging of the 2-3 cell lipo packs from 2200mah to 5000mah. For me being as close to the wattage as I am, pulling 840 constant @70 amps out of a 850w unit I fully expected to have some thermal issues and figured ide just charge at 60amps if it's having trouble delivering the 70a constant. But shockingly it handles 840w constant and has for two years or more without issues. Now I will say when the charger is in constant current part of the charging and it's putting out 70 amps of charge current the unit will get pretty dang warm but nothing to serious, at room temperature of 72F during a 70 Amp charge on 5000mah packs to where it's sustaining 840 watts of demand it will get up to maybe 110F but with a external fan blowing on it the temps will stay in the 95-100F range. For the 50 bucks I paid for the 850 gold it's been a mega good value for my needs. Reliable, quiet, smooth current delivery, very consistent voltage under high load... it's just been a dang good power supply as have both the 600w units in the back up gaming PC builds for my son and daughter. I never would have thought that the 850 watt gold would have been able to sustain 12v/70amp demand consistently as it's to close to its max wattage, I totally expected that I would have to back the current down to 60a so that would be around 720 watts for it to not have thermal issues with the power demands. It has done it for 2 years or more now and never skips a beat! If you have a computer build that needs a 850w supply I would absolutely say the 850w gold would do you a fantastic and reliable job! Computers put no where near the constant load on a unit as a high power lipo battery charger and it handles it without issue so I have no doubt it would do the same in a high demand PC build. I'm sure there are better built units out there, I'm sure there are units that deliver slightly cleaner power but at the price I don't think any other unit comes close to these. Buy one and you won't regret it, they are rock solid values and high performance units.

This power supply delivers lots of power to my motherboard and is extremely competively priced. I installed this bad boy and now all my usb ports are functional along with 3 hard drives. it is very quiet, all the cables, even the CPU cable reach to the top of my motherboard. This is a very nice power supply.
