Rated 3 out of 5 by from Good for a cheap computer Brought this when my Power Supply Unit failed and on the whole has done it's job until I upgraded my PC: My PC was an AMD Phenom II X6 with a GTX550ti graphics card. When I upgraded to an AMD FX8350 and a GTX770 graphics card it would work for general usage but if I played a recent game for an hour or my computer would get extremely hot and switch itself off. Taking the case off, I found that the Power Supply was hotter than the graphics card - It was barely touchable. Asked around on Forums and it seems that it advertises itself as a 780 Watt unit but that's the extreme most it can reach. If it's anywhere near that for a long period of time, it struggles and dies. Hope this helps

Rated 4 out of 5 by from This power supply is obviously a budget power supply. I picked it up cheap when it was on promotion. I am pleased with this power supply as it can run all my components with no problem and its silent under load. When it is not on offer your probably better off going for an antec true power psu. But over all this is a great power supply and its 120mm fan keeps the psu cool.

Rated 5 out of 5 by from This replaced an ageing, noisy and eventually faulty 400W power supply, supplied with the original case and at least 4 years old. Extremely quiet cannot hear it at all, has plenty of connectors for old and new systems, a bit tight on some cables but fitted all the same (mini tower). The system it is fitted to is an old SKT A AMD system with AGP graphic card but the power supply has all the connectors to be able to upgrade the motherboard later and has a supply for a pci-e graphics card. Fitted in less than 10 mins and comes with fixing screws (didn't use them used the existing old power supply fixings). On promotion when purchased, ordered 6pm Thursday evening delivered 9.30am next day Friday morning. Made up the order for free delivery cannot fault the unit or service well done Maplin.

Rated 3 out of 5 by from 2016 - Not fit for purpose I've had this PSU for several years now. It's still going strong, however, it is no longer fit for purpose. Previously powering a 6 core CPU, a GTX 560 and 3 HDD's it was absolutely fine. It's now 2016 and games demand a better G card, so I upgraded to a more powerful one. Due to a lack of knowledge I was unsure what the problem was when the card wasn't running efficiently and nearly every game was crashing. With a bit of research I found out that this PSU has 4 12v rails and that that is the problem. It simply just doesn't deliver the required power to support the card under normal load. I would advise any casual builder to do your research before purchasing this PSU.

Rated 3 out of 5 by from Good for a year I bought this about a year ago as my old Psu gave up on me, have been running this for about a year now and it decides today it wants to Overheat and send power surges through my computer... Luckily my MB's anti surge picked it up before anything was damaged but now my computer will only boot for about a minute before switching off again, Good for short term but might pay a bit more for something long term as I dont want to change my PSU every year!

Rated 5 out of 5 by from Very quiet I would hardly know it was on, and it seems to be running as it should. Took a bit longer to fit than I hoped, but that was probably because it was the first time I had fitted a PSU and the number of bits of kit in my PC's case that I was connecting to it. I will qualify this by saying that all this is said after only 12 days

a 760W power supply is more than enough to run that GPU and other components in the computer without any power issues

Hi, in continuation to a previous question. This PSU only has 2 x 6-pin PCI-E connectors, but I need 2 x 8-pin PCI-E connectors for a new GTX 980ti Strix. Can I just add 2 x 6 to 8 pin converters on? I really don't want to risk a bad job. Cheers!

Asked by: Bubba Jones
Whilst the converters you mention will give you the connectivity required, I would think that based on the info of your previous question you may be at the cusp of the operational ability of the power supply.

Looking to power a Strix GTX 980ti, I'm also running 3 fans, an Intel i5 2500, 500GB Samsung Evo V, a 2TB HDD, and some kind of Gigabyte motherboard, I have been using a GTX 970 without any problems, and 16GB of RAM...&nbsp; Will this GPU still do?

Asked by: Bubba Jones
I can't see how I'm supposed to power the card, it needs 2 x 8 pin PCI-E, and I've only got 2 x 6 pin, the 970 required a 6 pin and 8 pin, and I could get a 6 to 8 pin converter for one, but I'm apprehensive to upgrade both of the 6pins to 8 pins... Also the PSU only produces 600W in reality, and 780W under high load (max) and the last thing I need is to produce too much heat for no reason... Billy do you actually know how I'm meant to make the pins work? As the card suggests that I need to use two 6 pin PCI-E's to power one 8 pin...

Does this product have an 8 pin 12v EPS connector for the CPU? or just a 4 pin 12v connector?

Asked by: Ollie
It's only the 4 pin connector I'm afraid .
