Upgrade a hd 5750 on a i7 860 system

[Dearborn]

My system: i7 860, msi p55-gd65, 16gb ram gskill, radeon HD 5750, antec sonata iii case w/500w power, 2x wd black 1tb, 1x wd green 1.5tb, 60gb ssd c drive I am going to clone to a new Samsung evo 256gb ssd, windows 7 pro 64bit I will free upgrade to Windows 10 after c drive clone swap, a new wd black 2tb is in the mail to replace a 300gb drive, 1x USB 3 pci-e card, 1x bluray writer, 1x rme pci hammerfall audio card.

I'm going to upgrade the HD 5750 to another amd card to improve performance for steam games and rendering 4k real time in Sony movie studio platinum 13, which I was told works better with amd cards and opencl.

I was considering a r9 380 4gb saphire but am not sure if 500w is enough for my system, or waiting for Polaris in the summer. I don't really want to spend more than 200 on a card and could get something less but read that the the r9 380 is a best value now. My display is a 25" 2560x1440 dell. Playing games at 1080p looks fine usually which I have to set it to for reasonable fps on last gen games.

What would be a reasonable upgrade gpu?

What is the make and model of the PSU that you are currently using? When I add it all up I see the total system drawing 505 watts at 100% usage. If your PSU is a well rated brand, I could see you running the R9 380 without much issue. I feel that the R9 380 is as much GPU power as I would step up too with the aging I7 860 you are using.

GTX 960 if you don't want to buy a new PSU, unless that is a very high quality 500W PSU with two PCIe connectors.

I'm running an MSI Radeon 390 + Core i7-4790K with 4 120MM fans and two SSD's, plus 16GB RAM all on a gold 500W SFX power supply. I undervolt my 390 just a tad to keep maximum loads around 400W which still well within spec.

If you have a quality power supply with around 40 amps on your +12V rail you should be fine. You can always undervolt if necessary but the Radeon 380 uses considerably less wattage compared to a 390 so I wouldn't worry.

Those power supply calculators are very conservative.

Hey there Dearborn,

Your current system should be consuming around 350W and after upgrading it with the desired GPU it should jump to about 465W-470W which is pretty close to what your PSU can manage. I would be careful as this may lead to BSODs and crashes under heavy load.

As Madpacket pointed out you could try limiting the consumed power of your GPU and thus managing it with the current PSU but I would recommend considering a new and more powerful PSU with about 600W-650W if you want to be on the safe side. Storage drives shouldn't change the consumed wattage much. You can check the WD Black's power requirements in the drive's spec sheet here: http://products.wdc.com/support/kb.ashx?id=0BCy7k

Feel free to ask if you happen to have questions

I upgraded from HD5850 to R9-380x 4gb. The R9-380X has less power draw than the 5850, so of course it worked on my existing system just fine. I looked up the 5750 draw and it is a lot more than the r9-380x. I think the 380x power draw is improved from the 380, so make sure you're looking at the 380x card and should be fine.

5750 TDP 86W
5850 TDP 151W
r9 380X TDP 190W

That is a lot of watts ....... Just grab a 460 or 560 GTX, gl

If it's a prepackaged 500w it's likely the earthwatts ea 500d green.

if you buy a psu too watch out for it to be effiecent on at least 75% of the power draw dont look only for the 80 modu sign on them..
