I have a H50-55 and I am looking to upgrade my power supply.
Which power supply did you purchase?
Do you know if it fits the H50-55?
Is the old power supply easy to replace?

Do you think this one will work:
EVGA 500 W1 80+, 500W Continuous Power, 3 Year Warranty Power Supply 100-W1-0500-KR

1. You'll need to somehow adapt the pins of the new PSU to the Lenovo motherboard. To save money, I guess, Lenovo uses 14 pins instead of 24. This adapter worked for me, but you could also hack the PSU. The adapter's only $5.25, currently.
2. The Corsair CX430 worked in my Lenovo H50-55. It fit snugly. NewEgg.com lists its dimensions as 3.39" x 5.51" x 5.91". You can compare to the EVGA 500, or whatever you end(ed) up getting.

Thank you for your reply, I am defently getting the Corsair.
I am looking for a compatible video card, I do not do games, but some web design.
Do you think this card would be comapatible:
Gigabyte GT 420 2GB 128-Bit DDR3 PCI Express 2.0 x 16 ATX Video Graphics Cards GV-N420-2GI REV3

It's not a Radeon R7, so the GT 420 is not going to team up with the internal R7 processor in the A10-7800. It should be compatible, however. See videocardbenchmark.net. The GT420 appears at the bottom of the mid-range GPU list. The GT 430, GT 710, and GT 720 are all priced $30-44, yet are a good deal faster than the $40 GT 420.
Do you really need that speed, however? Maybe you've done it already, but I'd try using the internal graphics. After upgrading the PSU to the Corsair CX430, I tried some cards, but ended up with a dual monitor setup using the HDMI and VGA ports of the H50-55. It's been fine for editing, programming, writing, surfing, and occasional video or photo editing.
Even though I'm not using a video card, I'm still happy to have replaced the original PSU. It was only 180watts!

I tried two different power units today and the 4 pin that leads to the cpu did not fit properly. Is there a power supply that comes ready? Also, will a Radeaon RX 550 work with the H50-55?

The 4-pin plug to the CPU is an ATX standard, both a Novatech and a Corsair supply worked above in this thread. If you could post photos showing how your power supply plug is different from the two after-market supplies you tried, we could help you more. Thx.
