Hello, I know this card has been the most commonly suggested throughout my readings for those of us with 300w, but i'm curious if the case is the same for me. And if I got the card, would it run safe, able to over clock, i really wish I wasn't so computer illiterate.
My specs :
My PC model is HPE-510t ( I got it February 2, 2011 )
OS: Windows 7 64-BIT
GPU: Radeon 5570
Processor: i5-2300 CPU @ 2.80GHz (4 CPUs), ~2.8GHz
Wats: 300 ( I'm not too sure if I can find much more about it out HP support had nothing more to say. )
Your PSU is really bad, so I don't want to guarantee you'll do fine with overclocking. But you should be just fine. Your PSU should read how many amps it can provide on the +12V rail. If it's truly a 300W, it should provide 20A or more on the +12V rail. If it doesn't, then...well you'll probably still be fine. No guarantees though.
Why don't you just buy a $16 Corsair CX430? They go on sale for that price once a month and that can power up to a 7870 or anything with similar power usage (like GTX 560 or lower).
HP power supplies are of very poor quality.They can't deliver what it's rated for.It may say it's a 300 watt PSU but it's actually around 250 watts(maybe less).
Although even with a 250 watt PSU you should be able to run a 7750 with a i5-2300 but I wouldn't reccomenedit.Mostly for longeitivity sake.Just do yourself a favor and purchase a quality PSU you can count on.
HP doesn't expect most people that buy their PC's to add high end GPU's or anything of that sort.Maybe just a simple media card or something so they cheap out on the PSU.
Thanks! As long as it's a noticeable upgrade over my current 5570 I don't see a need on trying to overclock it.
I'd aim higher than the 7750 if I were you. It doesn't cost that much more to get a 6850 (often $120 after rebates), which has a sizeable performance jump. Of course, that would require a new PSU, which I'd prefer you get anyways. Have you considered the fact that the GeForce 600 series midrange cards should be out soon and should help you on prices?
For a system using a single Radeon HD 7750 graphics card AMD specifies a minimum of a 400 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 19 Amps or greater.
Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.
The HP OEM 300W PSU (my guess it's a Bestec ATX0300D5WC), with its +12 Volt continuous current rating of 19 Amps, is borderline sufficient to power your system configuration with a single Radeon HD 7750.
You have 19amps(228watts) on the +12/v rail(which is the only rail that matters really).With a 7750 and a i5 you'd be running right at around 200 watts give or take 10 watts.That's really cutting it close because it says it's only capable of delivering 228watts.But that's only what it says not what your PSU will actually put out.HP PSU's are really terrible so I have doubts that it can actually deliver what it's rated for.
The technical data says it will work but I don't think it's safe.If the PSU isn't sufficient you not only run the risk of loosing the PSU you run the risk of frying some componets.
Here's my suggestion.Save up some more money and get a quality PSU.You might even want to consider getting a higher end card like the 6850.It would go very nice with that processor.I see 6850's going for as low as $130 and you might be able to find a better deal on amazon.
Alright I think i'll just do that, I mainly want a better graphic cards before guildwars2 but there's still awhile for that. The only thing i'm afraid of is that i'll mess it up trying to install it. I have a HPE510t desktop, can anyone recommend a PSU that can run the 6850 card and that's easy to install.
