Hello,
A friend of mine, who works in a PC shop, provided me a new PSU (450W).
Here's the specs of the old one:
MAX POWER:300W
INPUT:100-240V / 6A,50-60Hz
OUT:
+12A ----- 12A
+12vB-----16A
+5,08V----13A
+3,3V----12A
+5,08VsB----2A
-12v----0,3A
The manifacturer is Delta Electronics.
Sticker of the new one: http://i46.tinypic.com/sxlp9l.gif
I couldn't find the manifacturer's site anywhere, but they told me it's an Italian OEM manifacturer.
Apart from the 150W increase, is it a decent upgrade?
Also, the new psu features a fan wich holds a whole face.
Should I aim it towards the top of the case or down? Down, right?
Is it worth to upgrade from the 300W/Should it handle an HD7750?
Thanks,
Amez.

I would be careful with a no-name PSU. If it goes bad you could potentially damage your other components.

As far as the 7750, AMD's website states that the minimum is 400W, so it should be good to go there.

Searching the lc-8460btx part number, I keep coming up with the Okia brand. Nearly every place that sells it says 'out of stock', which tells me it's probably a discontinued model. So then I searched for 'okia power supply' and started checking random links. A lot of those PSUs, of whatever size, also say 'out of stock'. I'm starting to think that Okia is no longer in business (but I could be wrong). If that's the case, good luck getting warranty coverage.

Do what kodeen said and get a brand-name unit. The PSU is the single most important component in your PC, so don't cheap-out on it. An extra five to twenty bucks, euro, whatever, will get you a quality-name PSU you can trust for a long time.

While I'm at it, if the value of the 12V sticker is "216W", does that mean that the actual summed load of components that the SPU will be able to hold is 216W?
That's the sticker: http://i779.photobucket.com/albums/yy77/yoda581/IMG_0083.jpg

If that's the case, I don't even need to upgrade. (The psu is from an hp pc and manifactured by Delta Electronics).
On a side note, I couldn't remove the old psu since HP kind of -stuck- it into the case...

That would be the total load capacity for the +12VDC rails. You have a bit more power available from the lower-voltage rails, as well.

Those old proprietary cases can be a pain to upgrade. Dell was notorious in the past for using custom power supplies that didn't fit any off-the-shelf standard. Sometimes when the OEMs did this, they'd also leave out the normal mounting holes that would allow you to put in an after-market case. I'll guess that n your HP there is probably some little tab that's next to impossible to find, locking the PSU in place.

Like the others definitely get a well known brand name.
Look for a PSU with Continuous Power not Max Power (or something like that - a lot of cheapo's only quote max power).You might pay a bit extra but the quality matters (i just replaced a el cheapo 750W a friend recommended which caused all sorts of problems til i replaced that with a Corsair 600W).
Also we dont know the rest of your system.Better to have more W free than not...

A quick note - The 7750 doesn't plug into the PSU, It draws power from the motherboards PCI-E slot.
Posted July 28, 2012
Aye, from the PCI-E...wich is one of the reasons I chose it, together with the 7700 series' flawless power management.
@nijuu
Rest of system:
-6GB DDR3 SDRAM
-HD7450 -> HD7750 (55W TDP, 75W worst case scenario) (20W overall increase over the 7450)
-i3 second gen (2200 @ 3.30 ghz) 65W TDP, 77W worst case scenario.
-Mother board: Foxconn 2ABF
-Stock 500gb hdd.
Now, let's assume everything is going at its absolute worst case scenario (never going to happen):
75W+77W+30W (Mobo+ram+hdd?)+20W (usb)
It's a gran total of 202W.
Btw, yesterday I've found this: http://www.tomshardware.co.uk/forum/343913-15-need-advice-upgraded-graphics-card
The user has my identical power supply, but his cpu consumes way more than mine.
And they suggested him the HD7750... so I guess a 20W upgrade isn't going to break the poor thing?

I managed to use put it in a build with a OEM Power supply so it shouldn't hurt that much. I must say though, they aren't very overclockable. (Mine won't overclock at all, its 880mhz factory overclock (Stock units are 800MHZ, i have a gigabyte HD 7750. - Apparently the 7750 should max to 900mhz core clock and 1250 memory and remain stable, but mine just wouldn't do it. I suspect that it's because of the massive fan Gigabyte mounted on it draws even more power from the PCI-e slot. Also - if your running a smaller monitor around the 20 inch size you should be able to run 1600x900 max on most games these days and still maintain 60 FPS.

Also, Im kind of jealous, your CPU is slightly better then mine :( (Im running an I3 2100 processor - They are a great series though!)

@nroug7
Aye, I've an HP 2011x (22''), so I will be running at 1660x900 :3
So, you managed to make it work with a oem power supply? Then that's great news for me!
I would be able to keep the 300W psu.
The 7750 I've bought is the HIS model (I want it SILENT...)...I suppose it will draw energy more or less equal to the Gigabyte.
I won't overclock for now, I don't want to take any risk with the PSU D:
And yes, the i3 2100 series is great! They draw 40W less than amd and deliver great performances.

Bought the HD7750!
So far, every game is running at native resolution and High settings :3
Thanks for your help!
